Strong parametric match from the same manufacturer in the same package, likely a direct replacement.
PRTR5V0U2X-N is a 2-channel, low-capacitance (0.35pF) TVS diode array in a SOT143 package for high-speed line protection. Finding a substitute requires matching the package, bidirectional configuration, and especially the low capacitance to maintain signal integrity.
SR05-N has matching electricals. Other parts have higher capacitance or clamping voltage.
Multiple candidates exist in the SOT143 package, but pinout must always be verified.
Direct replacement for PRTR5V0U2X-N should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The strongest candidate is SR05-N, which shares the same manufacturer and key specifications, suggesting it may be a direct replacement.
The main risk when substituting is increased capacitance, which can degrade high-speed signals. Alternatives with capacitance higher than 0.35pF are not suitable for the intended application without careful analysis.

| Channels | 2 | - | 2 | 2 — Number of channels matches. | |
| Clamping Voltage | 10 V | - | 12 V | 12 V — Higher clamping voltage provides less protection. |
Verified drop-in options for PRTR5V0U2X-N are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
